Methodology and results of studying soil moisture after the interaction with the operating devices

Abstract

Operating devices for soil cultivation in arid conditions should not carry the lower layers to the surface of the field, since this leads to the loss of moisture due to its evaporation. Purpose of work is to determine the moisture content in the soil after using new operating devices. There been developed technique of determining the moisture content in the soil after exposure to operating devices by studying the movement of soil layers in the vertical direction and comparing their moisture. The movement of soil in the vertical direction is quantified by a comparative study of the moisture content in the upper and lower layers of the treated formation before and after exposure to operating devices. Using appropriate equipment, there were determined the moisture content in the most susceptible to evaporation surface layer of 0–5 cm and then the average value of the layer-by-layer measurement up to a depth of 25 ÷ 35 cm, depending on the selected operating modes of the operating device.

The improvement of the technique for determining technical condition of repair and maintenance equipment

“…Therefore, the maximum removal rate of the removed metal is in direct proportion to the maximum allowable value of the depth of cutting for the considered repair equipment, taking account of the location of the cutter in its working space. [23] The technical level of metal-cutting equipment is determined with software using such a multifactor indicator as output [7], by calculating the machining cycle time of a conventional component:…”

Optimization of transport routes based on environmental indicators

“…To change the flow density for each load option, the value of the "Flow rate" parameter was changed in the program and was taken equal to: 150, 160, 170, 190 cars per direction. [31][32] From the graph shown in Fig. 9, it follows that with equal parameters, the "smart" traffic light gives a significant reduction in the queue length and waiting time at the intersection in comparison with the traffic light with a fixed cycle.…”

Combined process of vibratory processing and oxidation with the use of polymeric environments

“…Consequently, as a result of vibration wave action, the oxide film is loosened and smoothed during its growth. [32][33][34].…”
